At
@NASA
we have dedicated teams who watch the skies to make sure we are safe from hazardous asteroids. Today's asteroid flyby is one of the closest ever recorded, but our #PlanetaryDefense experts have been tracking the asteroid and know it's not a threat to Earth.

A newly discovered asteroid, named 2023 BU, is expected to make one of the closet approaches by a near-Earth object ever recorded. Thanks to diligent teams of #planetarydefense experts, we know It poses zero risk to Earth. Learn why: go.nasa.gov/3JfQi9W

Congratulations to the team at
@NASA
for successfully altering the orbit of an asteroid. The #DARTMission marks the first-time humans have changed the motion of a celestial body in space, demonstrating technology that could one day be used to protect Earth.

This just in: The #DARTmission impact is confirmed to have changed the orbit of moonlet Dimorphos around its asteroid Didymos. For the first time ever, humans changed the motion of a celestial object. More details: go.nasa.gov/3g2C5kp

Observations from
@NASAWebb
and
@NASAHubble
together will allow scientists to gain knowledge about the nature of Dimorphos, how much material was ejected by the #DARTMission's collision and how fast it was ejected.

.@NASAWebb & @NASAHubble caught the DART impact on camera – the 1st time that Webb & Hubble were used to simultaneously observe the same celestial target. Looking forward to what we’ll learn about #DARTmission from our telescopes on Earth soon.  nasa.gov/feature/goddar https:/
Side-by-side images of asteroid Dimorphos as taken by the DART mission (left) as well as the Didymos-Dimorphos asteroid system after impact from DART, as taken by the Hubble (top right) and Webb (bottom right) telescopes. DART’s view shows a close-up of the gray, rocky surface of the asteroid. Hubble’s view, colorized blue, looks like wispy blue streaks emanating from a glowing bluish white core. Webb’s view, colorized red, is positioned towards the bottom right of its frame. The core glows a reddish white, with red plumes spreading out from the center.
